21ic News Silicon Labs has announced the launch of its sixth generation iWRAP Bluetooth software for the Bluetooth 3.0 wireless audio accessories market. iWRAP 6.1 is Bluegiga's full-featured embedded Bluetooth stack, acquired by Silicon Labs earlier this year, designed to support the popular WT32i Bluetooth audio module. Target application areas include smartphone accessories, stereo and hands-free audio, cable replacement and Bluetooth HID.
The iWRAP software stack also provides a powerful and easy-to-use command line interface that enables developers to invoke such commands based on Bluetooth operations. iWRAP software makes the Bluetooth stack and configuration files no longer so complex, making them suitable for a wide range of applications, from simple audio and data applications to more complex use cases that require interaction with multiple Bluetooth enabled devices, even Multiple profile environment with synchronized audio and data connections.
iWRAP is supported by Silicon Labs' easy-to-use BGScriptTM scripting language. With embedded in each Bluegiga Bluetooth module, BGScript reduces the extra cost and complexity of using an external host MCU while isolating the software development kit (SDK) required for traditional Bluetooth development solutions.
New features supported by iWRAP 6.1 software include:
· Tone support: Tones (files) can be stored in the flash memory area of ​​the Bluetooth module, supporting playback of tone storage files.
· Tone mixing: Tones can be mixed into A2DP or HFP audio output
· Synchronize AVRCP controllers and target profiles: Improve user experience with the latest smartphones
· Enhanced user configurable Bluetooth reconnection logic
· Software Application Programming Interface (API) adds support for I2C interfaces
No wireless wireless development experience or tools are required to use the iWRAP stack. The software supports a UART interface, and the simple ASCII-based command and response API is easy to use and learn, greatly simplifying and speeding up the development of Bluetooth applications. iWRAP supports up to 7 simultaneous connections with data throughput up to 500kbps. The software can be customized and field upgraded via the UART interface.
iWRAP software integrates 13 profiles for data and audio applications, including AppleiAP1 and iAP2 profiles, supporting all Apple iOS devices in the market. iWRAP also supports the latest versions of Bluetooth audio profiles, such as AVRCP v.1.5 with media browsing capabilities, MAP profiles for SMS notifications and message downloads, and new aptX and AAC audio codecs for improved Bluetooth audio experience. Device.
Riku Mettälä, General Manager of Silicon Labs Wireless Module Products, said: "Mobile handsets are making wireless audio transmissions increasingly popular and continue to drive strong demand for Bluetooth classic audio solutions. As the leading provider of Bluetooth 3.0 solutions in the wireless audio accessories market. We have continued to enhance our iWRAP stack and have evolved to the sixth generation, in addition to supporting the latest Bluetooth audio features, while simplifying wireless development with easy-to-use tools such as our BGScript language."
Price and availability
The iWRAP software stack is now available for free to Bluegiga WT32i Bluetooth module customers.
